【摘要】：考虑基于社会力模型的多出口场馆的人员疏散问题.首先对社会力模型进行改进,包括个体之间的相互作用力和他们的相对位置有关,个体的期望速度随时间变化等.然后,针对多出口情形,定义动态变化的视野范围,综合考虑个体到出口的距离、个体视野范围内的人数和人群密度等因素,建立最优化模型描述个体选择目标出口的过程.最后,仿真结果表明,上述模型可以模拟出多出口的体育场馆中的疏散场景,该模型可用于体育场馆的建设评估及为现场指挥预案的制定提供依据.
[Abstract]:The evacuation problem of multi-exit stadiums based on social force model is considered. Firstly, the social force model is improved, including that the interaction between individuals is related to their relative position, and the expected velocity of individuals varies with time, and so on. Then, considering the distance from individual to exit, the number of people in the field of view and the density of population, the optimization model is established to describe the process of selecting the target exit in the case of multi-export, which defines the horizon of dynamic change and considers the distance from the individual to the exit. Finally, the simulation results show that the above-mentioned model can simulate the evacuation scene in multi-exit stadiums and stadiums. The model can be used to evaluate the construction of stadiums and provide the basis for the formulation of field command plan.
